I’ve mentioned this before but it’s worth repeating – walking, start with walking.
It’s free and can help you get to places you need to get to anyway.
10,000 steps is a good target to start with. This seems like a big number, and it is, but it’s very doable. It’s about 1hr 15mins a day. I’ve found that 5 mins each way home-station and 20 mins station-work is about 8000, it doesn’t take much to bump it up. There are some ideas here.
This alone will start to make a difference. Firstly your amount of exercise will go up – result! And , secondly it forces you to think about your activity levels, plan for it, make time for it – this is how we make space for more in the future.
Making this the first good habit you build sets a great foundation. It’s good for you and, if you’re walking instead of travelling by car, then so are your children and it’s good for them too.
